Stay in the clear

Barroom wisdom posits that clear drinks like vodka and gin induce fewer hangovers than dark ones like brandy, red wine, or certain rums and tequilas. At least one study bears this out: When researchers gave volunteers the same dose of alcohol in the form of either bourbon or vodka, only 3 percent of those who drank the vodka reported a bad hangover the next day, compared to 33 percent of the bourbon drinkers. Scientists suspect that the compounds in darker liquors are to blame.
